I haven't made a connection just yet, but I assume its a possibility.
Crate size- it is my labs large in size crate that I use for transporting him during season so it is plenty big for a Yorkie.
Feeding- we feed him a half a cup of food every morning which is the recommended serving per day.
Work schedule- I work from 8-5, leave before my wife and get home after my wife. I try to come home everyday on my lunch to let him out.
Purchase explanatory- my wife has been dying for a Yorkie for 2 years now, and they had 2 cheaply priced at our local fair so I pulled the trigger. All of my experiences of house training have been with labs and it has always been cake to get them up to speed. Even with a full time job
# deuces- yesir, 4 times a day....and he might weigh in at 3lbs
